Industrial-grade, sealed marine ignition switch with starter interlock prevents the starter from engaging while the engine is running. Protects ring gear and starter from abuse.

Maintenance displays:
• Engine hours
• Hours left before an oil change is due
• Fuel gauge & low fuel shutdown indicator
• High coolant temperature and low oil pressure shutdown indicators

Quiet - only 65 db (90Lwa) at idle and 73.8 db (98.7 Lwa)at 23 ft and maximum output. Improves work site environment and communication.

The VaultThe Vault-ultimate control board reliability in CC/CV models. Hardened solid-state control technology, housed in a sealed vault. The vault's sealed connections are made through watertight plugs that make these components impenetrable to dust and moisture.

Hot Start™ provides positive Stick electrode starts to make it easy to start all types of electrodes, and works great for bead tie-ins.

5,500-watt peak AC power that is independent of weld settings which means no interaction between tools and the welding arc.

Designed and built with reliable, heavy-duty industrial components to allow it to operate in remote locations without downtime.

Arc-Drive makes welding easy. Automatically enhances Stick welding, especially on pipe, by focusing the arc and preventing the electrode from going out.

Automatic engine shutdown protects engine if low oil pressure or high engine coolant temperature occurs.

Deluxe model includes: AC TIG to weld aluminum, engine gauges, weld meters and 15 kW three-phase power while not welding. Note: High-frequency control required for AC TIG welding.

CSA, IEC and NEMA compliant.
